Mesa OpenGL utility library (GLU)

GLU offers simple interfaces for building mipmaps; checking for the
presence of extensions in the OpenGL (or other libraries which follow
the same conventions for advertising extensions); drawing
piecewise-linear curves, NURBS, quadrics and other primitives
(including, but not limited to, teapots); tesselating surfaces; setting
up projection matrices and unprojecting screen coordinates to world
coordinates.

On Linux, this library is also known as libGLU or libGLU.so.1.

This package provides the SGI implementation of GLU provided by the
Mesa project (ergo the "-mesa" suffix).
